1 Claim.

This invention relates to footwear. More particularly, it relates to an inexpensive shoe and inexpensive method of manufacturing the same in which no last is required.

It is among the objects of this invention to provide a shoe in which the component elements of the shoe are assembled by stitching or gluing; to provide a shoe in which novel provision is made for holding a rigid sole support member in place; to provide, a shoe in which no last is required in assembling the component elements of the shoe; to provide a novel shoe in which the component elements are substantially all assembled by sewing or gluing; to provide a shoe including a novel pocket for a rigid sole support member; and to provide an attractive inexpensive shoe adapted for inexpensive and rapid manufacture.

These, and other objects of the invention will become apparent from the following description of a preferred embodiment thereof shown in the accompanying drawings, in which:

Fig. 1 is a plan view of the invention with portions broken away.

Fig. 2. is a side elevation view of the shoe illustrated in Fig. 1.

Fig. 3 is a longitudinal sectional view on the line 33 of Fig. 1.

Fig. 4 is a transverse sectional View on the line 4--4 of Fig. 3.

Fig. 5 is a transverse sectional view on the line 5-5 of Fig. 1.

Fig. 6 is a perspective view of an insole or filler sole forming part of the invention.

Generally speaking, the novel shoe of the invention comprises a filler or insole of fibrous material, cardboard or other like material, to which a piece of foraminous fabric, such as cheese cloth or cambric is adhesively secured. An elongated strip of fabric is stitched to the insole to form a pocket for the reception of a pre-formed rigid support or shank for the sole. In assembling the shoe, a sock lining is placed upon the upper side of the insole, and the shoe upper is placed on top of and properly positioned with respect to the sock lining. The upper, the sock lining, the insole, and the fabric member are then stitched together.

Previously, the preformed rigid support or shank will have been inserted in the pocket provided therefor. A binding is then placed around the edge of the assembled shoe elements in overlapping relation with the top and bottom of the assembly, and is stitched thereto. Subsequently, an outer sole of leather or other suitable material is adhesively secured to the portion of the binding underlying the insole and fabric member. During such assembling operations, no last is required. As a final step, a heel assembly is secured to the sole assembly by nailing or by any other suitable means; and a heel pad is adhesively secured over the sock lining.

Referring more particularly to the drawings, the shoe comprises a filler sole or insole II to which a matching piece of foraminous fabric l2, such as cheese cloth or cambric is adhesively secured. A strip l3 of suitable fabric is then stitched along both longitudinal edges to the underside of the insole to form a pocket to receive a rigid sole shaping member or shank M, which is pre-formed and may be of metal, plastic or any suitable material.

The insole is then placed in a position with the shank underneath, and a sock lining I5 of suitable fabric material is placed on the upper side of the insole. The shoe upper I6, which may be of any desired configuration, in accordance with the type of shoe to be manufactured, is then placed on top of the sock lining. The shoe upper is formed with a flange I1 along its outer lower edge, and this flange I1 is then stitched to the sock lining, the filler or insole, and the fabric member l2.

To complete the sole assembly, a binder 20 of suitable material, such as patent leather, oilcloth, or treated fabric is then placed around the insole and uppenand bent into the shape of a U so that its upper and lower edges 2| and 22 overlap the edge of the insole and the upper. The binder 20 is then secured to the assembly of the upper and the insole by stitches 23 extending completely through the hinder, the upper, the insole, and the fabric member I2. The lower edge 22 of the binder is then adhesively secured to an outer sole 24 of leather or other suitable wearing material.

The completed sole and upper assembly 25 is placed with its rear portion on top of a heel assembly comprising a heel body 26, which is enclosed by a binder 21 and to the bottom of which a lift or heel plate 28 is secured by nailing or other suitable means. The heel assembly 29 is then secured to the sole and upper assembly 25 by nailing or by any other suitable means. As a final step, a heel pad 30 of patent leather, oilcloth or treated fabric is adhesively secured to the upper edge 2| of the binder 20 at the rear end of the sole and upper assembly, and overlying the nails 3| securing the heel assembly to the sole and upper assembly.

Due to the fact that the component elements of the sole and upper assembly are secured together either adhesively and/or by stitching, no last is required during the operation of forming the sole and upper assembly 25. The fabric member I2, adhesively secured to the lower side of the filler or insole ll, acts as a retaining and securing member for the filler sole or insole.

A novel feature of the invention is the provision of the strip l3 sewed along its longitudinal edges on the lower side of insole II. This strip [3 forms a pocket for retaining in place the member or shank [4 which holds the sole assembly in its predetermined shape.

While the shoe is attractive in appearance, and has good wearing qualities, the major part of its component elements are formed of relatively inexpensive material which is protected from Wear and attack by the elements by the binder 20 which is stitched to the sole assembly. From outward appearance, it is substantially impossible to distinguish the shoe of the present invention from one formed of much more expensive material or construction. The shoe of the siderable salability because of its attractive appearance. Additionally, the economies in manufacturing costs due to the elimination of the necessity for using a last to assemble the sole and upper assembly, as well as due to the assembling of the sole and upper by adhesives or by stitching, contribute materially to the usefulness and desirability of the invention.

While for purposes of illustration a specific embodiment of the invention has been shown and described in detail, it will be apparent to those skilled in the art that the invention may be otherwise embodied without departing from the principles thereof.

What is claimed is:

The method of manufacturing shoe soles, comprising providing a filler member, adhesively securing a matching piece of foraminous fabric to the lower side of said filler member, then stitch: ing an elongated fabric strip to the lower side of said filler member adjacent the shank portion thereof to form a pocket for a sole stifiener, and inserting a sole stiffener in said pocket, whereby to provide a sole to which a sock lining and. shoe upper may be stitched.
